[[ The principal task of the RDF Data Access Working Group is to gather requirements and to define an HTTP and/or SOAP-based protocol for selecting instances of subgraphs from an RDF graph. ]] http://www.w3.org/2003/12/swa/dawg-charter#scope was a very motivating charter sentence for me to join this group and was also a reason why I abstained in the "bindings" vote. Since then I learned to live with it... Having list comprehension axioms (one can assume the existence of rdf lists containing all kinds of rdf resources) one can as such augment the given graphs with list triples and still have just "selecting instances of subgraphs from an RDF graph" e.g. (:a :b :c) a q:Answer. where it is assumed that q:Answer rdfs:subClassOf rdf:List. Using lists is also quite compact using rdf/n3 ( ) or RDF/XML rdf:parseType="Collection". The point I wanted to make is that the query answer can always be an RDF graph. -- Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/
